Abstract
The present disclosure provides a method of data protection for a NAND memory. The method includes programming first and second pages of a NAND flash memory device according to programming data such that data stored in the first and second pages are redundant. The programming of the first and second pages includes a plurality of programming operations using a plurality of programming voltages and a plurality of verifying operations to determine whether programmed memory cells of the first page have threshold voltage levels according to the programming data. The method also includes determining a completion of the programming of the first and second pages based on each of the plurality of verification operations returning a pass result. The method also includes performing, after the determining, a read operation on the second page by the NAND flash memory device to self-verify the data stored at the second page.
